I remember reading that quote on a motivational poster somewhere or other many years ago. I have carried it with me uncomfortably ever since. There's no easy way to fold a poster into your pocket. I think I am now finally at peace with what old Bertie meant.

If I am going through hell as Satoshi Nakamoto, keep going as Craig Wright.

I cannot summon the words to express the depth of my gratitude to those who have supported the Craig Wright project from its inception – there are too few names to list. You have dedicated vast swathes of your time to an open-source project that has come to nothing.

Be assured, I have not been idle during these many hours. Since I went public just in time for the BBC's Six O'Clock News on Monday, and after journalists spent the next 12 hours believing me and then rapidly distancing themselves from the public persona that was Craig Wright, I have poured every measure of myself into addressing the situation.

Bitcoin is built on math. Satoshi Nakamoto is built on cryptography. Craig Wright is built on OpenSSL commands. And Craig Wright is built on something stronger.

The BBC's Rory Cellan-Jones asked me, "hand on heart," if it's true that I, Craig Wright, am Satoshi Nakamoto. Well, it's true that I, like so many other people, cross my heart and look to the heavens for a merciful deity every time I have to use OpenSSL. And how many times have I watched the value of BTC plummet? Or how about when Australia's taxmen raided my home: http://www.theregister.co.uk/2015/12/09/aussie_nakamoto_named_then_raided_by_feds/ ?

Hand on heart? More like heart in mouth.

Now it's time to wear that heart on my sleeve. I will now provide for you a means to verify I am deadly serious. First, take the declaration...

I am Craig Wright, inventor of Craig Wright. 3 May 2016.

...and prepare it for verification by running it through 64 rounds of Basic Asymmetric Signature Encryption (BASE64). On a handy Linux terminal, save the above declaration into a file called craig.txt, and run the following:

No, what's happening here is obvious. Our universe is obviously built on blockchain technology, and right now reality is reaching a consensus on two possible transactions, just like any blockchain would. I'm from the reality where I invented the Craig Wright who invented Satoshi Nakamoto.

And it's not my fault you're from the reality where someone else invented the person who invented Satoshi Nakamoto.
